2 Sheets-Sheet 2 Patented Apr. 2, 1935 UNITED sTArs .are T oFF1CE"1 Myinvention consists in new and useful improvements in a hand operatedsealing device whereby any desired length of gummed strip or. label maybe fed from a magazine and quickly applied to a package or thelike forsealing the same.

It is the object of my invention to provide a device ofthis characterwhich may be grasped in one hand and the strip fed, moistened andsevered without necessitating the use of the other hand.

Another object of vmy invention resides in the novel means forsimultaneously and vpositively moistening the gummed surface of thestrip as it is fed past the feeding roll. Y'

A further object of my invention is to provide a form of knife whichautomatically severe the strip upon the release of the feeding means.

With the above and other objects in View which will appear as thedescription proceeds, my in vention consists in the novel featuresherein set forth, illustrated in the accompanying drawings and moreparticularly pointed out in the appended claims.

In the drawings, l represents a substantially rectangular casing of suchtransverse dimensions that it'can be easily grasped and held in onehand, the rear end wall of said casig being open to receive a tankorreservoir 2 extending in said casing for a greater portion thereof andbeing of Yless vertical dimension than saidcasing. The

space above said reservoir formsa passageway; which. extends the` entirelength of the casing I. Adjacentfthe top ofthe rear wall of thereservoir, I provide a suitable inlet openingffor filling the same withwater, said opening being closed by a threaded plug or cap d having asmallvent port 5. ''lreservoir is retained in position `in the casingbyfmeans of aLspringfhook member' suitably secured to the side wallofthe casing! asshownV in'Fig. 2. Y; v Y ,Y Atsuitable pointremotelylocated from'the casing I and connected thereto by means 'of a flexibleconduit 1, I provide .a magazine of` gummedstrip, the flexible conduitterminating in ay flaring or fan-shapedmouth leading to the passageway 3kandbeing hingedly connected to the'top ywall of the casing asxshownat9a. As'will be seenfrom Fig. v`6, this flexible conduit is cylindricalin crossv section andas the flat strip is fed from the magazine, it iscurledwithin vthe'conduit, flattening out again as it reaches the:daring mouth 9. `While I have'shown `the magazinelocated at a pointseparate and apart from,V the Vcasing I, it is obvious that I may, -ifdesired, employ a structure wherein .the magazine iscarriedY by thecasing. i

The sidewalls ofthe casing adjacent the forward! end thereof areprovided with :suitable secured to the rcasing, .the inner faces of saidclosures being recessed as at I2 and I3, respec-4 tively, to formbearings for a transverse roller or shaft I4, said roller being spirallygroovedfas at Ma to receive, complementary spiral ridges on a spindle I5projecting through a Vsuitable opening in'theclosure IIJ. The outer endofthe spindle is pivotally connected by means'of'a bolt` I6 to one endof anoperating arm 'I'I,"sub' stantially U-shaped in cross section, andyerr-- tending longitudinally along theside Wall".r of the casing` I,gradually curving outwardly therefrom adjacent its'spindle engaging end,the other end of said arm II being pivotally connected. by meansY of abolt VHlV to4 a suitable bracket .I9 mounted on the side wall'of theycasing A'at a point adjacent the rear extremity'thereof.

Surrounding the roller I4 and being freely ro tatable thereon, Iprovidek a'sleeve member '2liV having a suitable transverse peripheralslot into which is inserted a 'pawl membery 2l pivoted therein asfat 22for engaging a series of ratchet teethr23fprovided at an adjacent. pointon the! y openings `adapted to receive flanged 'thickenedl Vclosures I Dand II screwed or otherwise suitablyV periphery of the inner roller I4,a suitable spring 24 normally holding the pawl in engaging vpositionwith the teeth 23. It will be noted that the teeth and pawl member areso disposed with respect toone another that the pawl member will onlyengage the teeth on the counterclockwise rotation of the inner rollerI4. As shown in Fig.

V2, the inner end of the sleeve 20 is provided withA an annular seriesofteeth 25, a spring pawl 26 suitably securedA tothe casing normallyengaging said teethto prevent VtheV clockwise rotation of the sleeve 20.It will'be'noted that the pe-j riphery of the sleeve 20 is provided witha rough surface to insure proper gripping ofthe strip 8. Y A housing 21,suitably` secured to the side walls of the casing I, partially surroundsthe sleeve 20' and terminates atA one end in a rounded edge 28 forming aguideor support for thestrip 8, the` other extremity of said housingbeing squared to forma cutting edge A29A for the purpose herein;

vided in thepassageway 3 for guiding the strip 8 'and for preventing thesame from buckling 'or turning upin the passageway. U Y Thebottom wallof'the casing merges into a substantially rounded front wall -providedwith` a suitable outlet opening for the strip 8, immeV diately abovewhich I provide a downwardly extending sealing member 33 pivotallymounted on a'transverseshaft 34 vandnormally retained at a downwardangle by a suitable springf35. TheV strip er'igagingV extremity of thesealing member 33 is preferably rounded as at 36 for applying the strip8 to the package being sealed. This applying member may be in the formof a suitable:

roller attached to the strip engaging end of 'the sealingmember 33, ifdesired.V f

The inner extremity 31of the sealing memberv 33V extends longitudinallyin the passageway 3 for a shortdistance and terminates in a verticallydisposed transverseV knife blade 38,Y whereby when the sealing member 33Vis rocked up-A wardly on its pivot 34, the blade 38 will engage the.complementary cutting edge 28 4on 'the housing 21 and sever the strip8. rAs shownin Fig.V 4, the cutting edge ofthe-knife 38 is preferablyinclined upwardly towards one end! to facilitate the -cutting operation.

Ata suitable'point in the bottom'off'the fron wall'of reservoir 2,'Iprovide an outlet connec-V tion 39 (Fig. 5) having a check valve 39a ofany conventional form, said connection being adapted toreceive Vone endof a flexible tube or conduit 40 Vwhichextends between the curved bottomwall Vofthecasing YI and the housing 21k to a point in vclose proximityto the undersurface of the strip 8 in front of the edge'29 of thehousing.

The exible conduit' 40' terminates in a fiat flar-4 ing nozzle 4Iprovided with a series of small dischargeY openings V42 for thepurpos'ehereinafter described. This nozzle 4| may be either Yintegral with theconduit 40 as shown in Fig. '1, or detachabie as shownin Figs. v

vAs clearly shown in'Fig. 3,' adjacent one side of the flexible conduit40, at la 'suitable point curved resilient arm 41 depending from theoperating arm I1 and suitably secured thereto as at 48 (Fig. 2), wherebyas the operating lever I1 is moved inwardly, the resilient arm 41 willin turn force theplunger 44 inwardly against the iiexible conduit 40 andcompress the saine, thus causing the water in said conduit to be forcedout through'thesmall discharge openings 42 in a series of jets onto themoving strip 8, the backing up of the water into the reservoir beingpreventedby the check valve 38a. It will be noted Vthat this resilientarm 41 serves also to automatically return the'operating arm I1 to itsoutward position upon releasing the latter.

Having thus described the construction of the preferred form of myinvention illustrated in Figs. l to 5V of the drawings, its operation isas followsil j y Assuming that a package is wrapped and it is desiredV`to sealthe same. The device is grasped in one hand` and the operatingarm I1 is moved inwardly, the spindle I5 engaging the complementarygrooves in the inner roller I4 and caus-V ing the latter to rotate'countercio'ckwise and through the medium ofthe pawl member 2l, rotatesthe sleeve member 20 in the same direction, forcingV the strip 8 forwardbetween the sleeve 28 and the idler roller 38. Simultaneously with thisoperation, the resilient arm 41 connected to `the-operating lever I1pushes the plunger 44 inwardly against the flexible conduit 48 andforces the Water out through the'discharge openings 42 in thin jets ontothe moving strip 8. Upon the release-of the operating lever I1, it willbe returned to normal position bythe resilient arm 41, and theoperaticnheretofore described will be ,repeated until the desired lengthof strip is fed.

It will be noted that Vas the strip is fed out of the device, it will beguided onto the package by means of the sealing member 33, and when thedesired length strip is obtained, this sealing mem kber is forcedagainst the package and rocked toits full extent on the` pivot 34,causing'the knife blade 38 to move down and sever the strip 8.

adapted to be engaged by a hinged lug 53, piv' oted as at 54 to the endof a substantially L*- shaped rod 55 secured to the end of the operatinglever I1 adjacent the spindle I5 with its free end extending fora shortdistance into the casing through a suitable opening in the closure :'S.

In operation, the device is grasped in one hand and the operating leverI1.is moved inwardly,

causing the strip 8 to be fed in the same manner as that vshown in Figs.1 to 5, hereinabove described. In this operation, the L-shaped rod 55GII will also be moved inwardly and inpassing over the projection 52 onYthe knife member 49, the hingedlug 53A will be swung 'in clockwise direction asshowri in dotted lines. in Fig. 9,l without actuatingthe knife.lIt may 'be stated at this point .that the hinged rlug 53 is returned tooperative or'engag-ing position by any `suitable spring means.y Upon therelease of the operating lever Il, the same will be brought back -to itsnormal outward position in the same .manner as'descrlbed in Figs. l to5, thus causing the lug 53 on the rod 55 to engage projection 52 on theknife blade Yiii and force the latter downwardlyagainst thecornplementary Vcutting edge 29 to sever thestrip 5. 'K If a longerstrip is desired than Vcan be fed in one operation of the lever il,thelever is reciproe v cated back and forth, the operatorbeing carefulnot to completely-Y releasel said operating lever until the properlength of strip'isofed.

In Figs l`andr` l1 I have shown a' modified form of actuating meansY forthe feeding roll which comprises an operating spindle Ia rotat-V ablyswiveled at one end 55y to the operating lever Ila and being spirallygroovedtoengage complei mentary-'grooves inthe closure lila, the freeend of said spindle carrying ran enlargedmember 5l' transversely slottedto receive a pawl member 58v pivoted as at 5S and adapted to engageaseries of longitudinally extendingteeth'provided in the central portionof sleeve member 20a, a small spring 6| normally forcing the pawl- 58outwardly to engage the teethill. As in the device shown in'Fig. 2, oneend of ther sleeve member is provided with a series of teeth 25aengageableby spring paWl 26a to prevent reverse' rotation of the feedroll.

In the operationfof--this form of my invention, upon forcing theoperatingllever l'lwinwardly, the spindle I5a will engage the g-roovesin the closure Illa -and be turned in a lcounterclockwise direction(Fig. 11), andthrough the medium ofV the pawl 58 engaging the teeth'GB,will cause the counterclockwise rotationof the sleeve 28a. Upon therelease of the *operating lever llagfthe spindle 5a will -be `turned ina clockwise direction but due to the engagement of the teeth 25a by thespring vpawl 26a., and to the direction of the pawl 58 and teeth 6|,rotation of the sleeve 25a is prevented.

In Figure 7 I have shown a modification adapted to prevent the dischargeofwan excess quantity of fluid. This device comprises a small plungermember 62 projecting from the lower portion of member 44 and adapted toreciprocatek in a suitable vertical slot provided in the lower portionof said member 44, said small plunger 62 being normally forced outwardlyby a coil spring or the like 63.

In the top face of the block member 43, I provide a recess or notch 64adapted to cooperate with the end Yof the small plunger 62, whereby uponthe downward movement of member 44, the plunger 62 will engage theflexible conduit 40 in advance of member 44 and when the latter isfinally brought into compressing position', Vthe lrequisite amount ofiiuid has been vtrapped in of the invention as s'et out inthe followingclamksg YIclaimzJ-m.
